Review: Great sound quality and volume, long battery life! - I teach workshops inside loud venues, like breweries, and I wasn't sure if this would be loud enough for what I needed, but it has worked great! Even with a group of 30 or more people in a large outdoor space, everyone can hear me well. I used it for at least 5 classes (2 hrs per class) and the battery still didn't need to be charged. Worth every penny, and I wish I'd bought it sooner!
Review: Love this mic! Lasts a couple years with continuous use! - Update! I just bought a second one. The design is slightly updated. Works like a charm. Hoping to get 2 more years out of it! I bought a different one recently, and that broke after 2 months (the strap broke the first week. Not this product! I'm coming here to give this item 5 stars. Will update with how long it lasts me this time around! This cute little mic lasted me 2 years of continuous teacher use before glitching in me. So sad. I loved it.

It's really a nice item, however it doesn't really work for outside use. It doesn't filter out the wind noise.
